HEAD FonoiL-LWELLS.

To all 'whom t may concern."v

Be it known that I, FRED J. MOSER, a citizen of the United States, residing at Kane, in the county of McKean and State of Pennsylvania, have invented new and useful Improvements in Heads for Oil-Wells, of which the. following is a specification. j

This invention relates to heads for oil wells and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

It is desirable to so close the casing heads of oil wells as to prevent the escape of gas. Among the reasons for this is the saving of the gas. itself and also the prevention of fires and consequent injury to the parts by reason of the ignition of escaping gas. It is desirable to accomplishv this sealing of the head around the tubing in such a manner 'that the tubing may be readily withdrawn and also. in such manner that the-vibration due to the pumping action will not open the joint. It is 4also desirable to so form` the connection in the 'tubing as to prevent the breaking of the joint with the tubing and the consequent dropping of the tubing into the well. I

The present invention includes among its objects the improvement of the oil well head to obviate the difficulties just described.

' panying drawings as follows The invention is illustrated in the accom- Figure 1 shows -a central section through the head. Fig. 2 a plan view. Fig. 3 a side elevation of the head.

l marks the casing head and' 2 the casing, the casing head being screwed on the top of the casing in the ordinary manner. Gas lines 3 extend from vthe sides of the casing head. Tubing 4 and 5 are secured to the tubing support 6, the tubing 4 being suspended in the well by the support and the tubing 5 extending to a discharge connection. The tubing support is of considerable length andhas an` annular'iange 7 which rests on a seat 8 surrounding the opening 9 in the top of the casing head. A packing 10 is preferably arranged between the flange and seat 8 and in order to better retain this packing an4 annular {ia-nge 11 is preferably arranged on the flange 7 forming with the `support', 6 a groove into which the packing or gasket is crowded by the weight of the parts supported by the support 6 on the seat 8. The opening 9 is larger thanthe Specication of Letters Patent.

tubing 4. The purpose of this is to permit the removalv of the couplings ordinarily,

used with tubing-through the opening. This forms a tight gas joint which will not be loosened in the ordinary pumping action. The joint is subjected to the direct weight of the tubing and is of large enough diameter from re so as to prevent the dropping of the tubing .into the well. This extended length of the support also assists in sustain-- ing the vibrations due to the pumping action. It is frequently necessary to lremove the tubing from the well and before doing so, the packing must be removed from the stul'ling box of the ordinary head so that the couplings on the tubing may be pulled up through the head and as the packing has been tightly wedged in the stuiling box by the great weight of the tubing suspended by the top coupling resting on the gland, the packing is very diflicult to remove. With the present device the acking simply lifts oii' the seat and the di culty just described is entirely obviated. The joint with its paclng is entirely protected from the weather by reason of the cap formed by the flange 7. j

It will be understood that the ordinary sucker rod extends through the tubing 4 Where the well is being pumped.

What I claim as new is 1. The combination of a casing head having an openingfthrough its top and a raised seat around said opening; and a tubing supportv extending ,through said opening having a flange forming a joint with said seat, said support having a screw threaded opening in its top and bottom for connection with the tubing.

a tubing-couplingjadapted to be suspended from the support, said support having a screw threaded opening in its top and bottom for connection with the tubing.

3. The combination of a casing head hav ing anopening through the top and a raised seat around said opening; and a tubing support extending through the opening a d1stance to make the joint with a tubing at the 4. The combination of a casing head hav-y ingan opening through the top; araised seat around'said opening; a tubm support extending through said o ening avmg a fiange forming a ljoint wit said seat; said support having a screw threaded opemngin its top and bottom for connection with the I tubing, and a gasket'between the surfaces of the joint.' g

` 5. The combination of a casing head having an opening through the top; a ralsed seat around said opening; a tubmg support 2o extending lthrough said opening and havin a grooved ange forming a jomt with sai seat; said support havinga screw threaded opening in its top and` bottom for connection with the tubing, and a gasket arranged in 25 said groove. l A

In testimony whereof I have hereunto set my hand inthe presence of two subscribing witnessea FRED 4JOSEPH MOSER.
